Never heard of a Worm drive clamp backing off on it's own. Physically impossible I'd say.

Plastic hose under pressure from the clamping system, cold flows and no longer seals whether on the suction side or pressure side of a system.
Think all those leaky air lines on a semi or compression fittings on water lines. Even the rubber radiator hoses lose resilience and develops a compression set with time and eventually leaks antifreeze.
Net result is that if you use spiral clamps it is good practice to re-tighten them if you wish to avoid a leak. Part of my spring ritual for my dump truck, other vehicles and the head in the sailboat.
The above doesn't help if the spiral clamp was not installed on the hose barb fitting correctly. Two clamps, one near the end of the hose once all the way on the hose barb, the other near the end of the hose barb farther back on the hose, is a better practice than a single clamp. Even better is to use a different seal design altogether.
This is BS, I work with hose clams everyday and what your saying is just not right. I have never in my 55 years have had a hose clamp loosen up! hoses fail rubber breaks down plastic cracks but Hose clamps do not back off on there own.
^^^^ maybe I'm missing something, but I'm pretty sure you're calling 'BS' on someone that wrote exactly what you stated. BB wrote "The hose clamp doesn't loosen".

Brads answer totally blows my mind, Hose Clams do not loosen or they wouldn't be using them almost everywhere, Cars, Trucks, Boats, and so on. I would Call him on the phone and have him lie to my face so I could tell him off

How is that 'A Devastating Discovery'?
Looks like the fill line came off and the vent line is not connected.
Something to be expected when you let someone else work on your stuff.

No they don't. If they did, nobody would be using them since the results are devastating. Nothing loosened here that wasn't already loose. Workmanship, pure and simple.
